ObjectiveGlobozoospermia is a rare type of teratozoospermia with incidence of 0.1% among infertile individuals. Phospholipase C zeta (PLCζ) and postacrosomal sheath WW domain binding protein (PAWP) are the main candidates in sperm taking responsibility for oocyte activation during fertilization. Therefore, we aimed to evaluate the expression of these two genes at RNA and protein levels in globozoospermic individuals and compare the results with fertile individuals. Materials and MethodsIn this experimental study, semen samples of 21 infertile men with globozoospermia and 25 fertile men were collected. Expression of PLCζ and PAWP at RNA and protein levels were assessed and compared between two groups by quantitative real time polymerase chain reaction (qPCR) and Western blot, respectively. ResultsExpression of both PLCζ and PAWP were significantly reduced at RNA and protein levels in infertile men with globozoospermia compared to fertile men. ConclusionThis is the first study that simultaneously assessing the respective factors in a large population of globozoospermia, suggested that intra-cytoplasmic sperm injection (ICSI) along with artificial oocyte activation may rescue failed fertilization in routine ICSI.
